The global push toward net zero is reshaping industries, and pharmaceutical manufacturing is no exception. As climate change intensifies, companies face mounting pressure to reduce their carbon footprints while maintaining operational excellence. In this complex environment, the pharmaceutical sector must navigate stringent regulations, high energy consumption, and evolving technologies—all while adhering to strict standards for product quality and safety.
EECO2 is leading the charge in this transformation. By integrating Pharma 4.0™ principles and optimizing HVAC systems, we provide tailored solutions that help pharmaceutical manufacturers balance sustainability, regulatory compliance, and financial realities. This article explores the global journey toward net zero, key challenges in pharmaceutical manufacturing, and how EECO2’s solutions—including contributions to the ISPE Good Practice Guide: HVAC – Second Edition—are driving the industry forward.
The drive to net zero began with the Kyoto Protocol in 1997, the first international agreement to set binding greenhouse gas (GHG) reduction targets. Though it was a landmark in climate diplomacy, it soon became clear that the protocol lacked the scope needed to address the growing threat of climate change. Global leaders recognized that more ambitious efforts were required.
The turning point came in 2015 with the Paris Agreement, where 196 nations committed to limiting global warming to well below 2°C, with efforts to limit it to 1.5°C. To achieve this, countries agreed to reach net zero emissions by 2050. The agreement includes Nationally Determined Contributions (NDCs), which are revised every five years to reflect growing ambitions and progress.
The Paris Agreement also emphasised the need for climate finance, ensuring that wealthier nations help fund the transition to clean energy in developing countries. This set the stage for significant changes in industries, especially energy-intensive ones like pharmaceuticals.
The UK was the first major economy to legislate its net zero target. Under the Climate Change Act (2008, amended 2019), the UK aims to cut emissions by 78% by 2035 and achieve net zero by 2050. These legal mandates push industries to adopt cleaner technologies and improve energy efficiency.
UK Emissions Trading Scheme (UK ETS):
This cap-and-trade system incentivizes industries to reduce emissions by allowing companies to sell surplus allowances, encouraging investment in low-carbon technologies.
The European Green Deal outlines the EU’s strategy for achieving climate neutrality by 2050, with an interim goal of reducing emissions by 55% by 2030.
EU Emissions Trading System (ETS):
The ETS is the world’s largest carbon market, covering about 40% of the EU’s emissions, including those from power, industry, and aviation.
Energy Efficiency Directive (EED):
This directive mandates energy efficiency improvements across industries, ensuring companies adopt energy-saving measures and reduce carbon output.
With its re-entry into the Paris Agreement, the U.S. set ambitious goals for reducing emissions by 50-52% by 2030 and achieving net zero by 2050. The Inflation Reduction Act (2022) earmarks $369 billion for clean energy, making it the largest climate investment in U.S. history.
Clean Air Act:
The act regulates GHG emissions and pollutants, encouraging industries to adopt cleaner processes and technologies.
Carbon Reporting:
U.S. corporations are increasingly required to disclose their carbon footprints, driving demand for sustainable practices across industries.
As the largest emitter of CO2, China has committed to peaking emissions by 2030 and achieving net zero by 2060. China’s Five-Year Plan emphasizes renewable energy and the decarbonization of heavy industries like pharmaceuticals.
Carbon Trading Scheme:
China’s national carbon market, launched in 2021, initially covers power generation and is expected to expand to more sectors, providing financial incentives for emission reductions.
India, a growing economy, faces unique challenges as it balances development with climate goals. The country aims for net zero by 2070, with a focus on improving energy efficiency in industries like pharmaceuticals.
Perform, Achieve, and Trade (PAT) Scheme:
This initiative incentivizes energy efficiency in large industries, promoting the adoption of clean technologies and reducing GHG emissions.
As outlined in the Challenges for Net Zero Carbon Pharmaceutical Manufacturing article(KB Article – Challenges…), the pharmaceutical industry faces unique challenges in its decarbonization journey. The sector is responsible for 20% of healthcare emissions, and while many companies have set ambitious targets, there is often a gap between goals and tangible results.
Scope 1 Emissions:
These are direct emissions from fuel combustion on-site, such as natural gas used in sterilization and heating processes. Reducing these emissions is challenging, particularly for companies reliant on high-temperature processes.
Scope 2 Emissions:
These include emissions from purchased electricity used to power HVAC systems and cleanrooms. Companies can reduce scope 2 emissions by adopting renewable energy sources and optimizing energy usage.
Scope 3 Emissions:
Scope 3 emissions are the largest share for most pharmaceutical companies, covering the entire supply chain. Engaging with suppliers to promote sustainability and reducing transportation-related emissions are critical components of scope 3 strategies.
The path to net zero comes with significant financial hurdles. While investing in sustainable technologies can be expensive, the long-term costs of inaction—rising carbon taxes, regulatory penalties, and increasing energy prices—are even greater.
Energy Costs:
HVAC systems account for a large portion of operational costs in pharmaceutical manufacturing. As fossil fuel prices rise, companies that fail to invest in energy efficiency will see their expenses increase.
Carbon Pricing:
With carbon markets expanding globally, companies that do not reduce emissions will face higher costs. In regions like the EU, carbon prices are already at record highs, and similar systems are being developed worldwide.
